摘要：

This paper proposes a novel energy harvesting and power management circuit that includes maximum power point tracking (MPPT) circuit, energy storage circuit, energy instantaneous discharging circuit, and DC-DC boost converter. It harvests energy from indoor faint light by imposing the harvester to work close to its maximum power point and supply power for sensor node. The measured result shows that the prototype circuit can harvest energy from indoor light condition with input power of 72.74 mu W and successfully drive a smart wireless temperature and humidity sensor node with power consumption of 105mW per operating cycle.
